Pharmacologic Category: Vitamin, Water Soluble

Mechanism of Action:   Coenzyme for various metabolic functions, including fat and carbohydrate metabolism and protein synthesis, used in cell replication and hematopoiesis


Mood Health: Acts as a methyl donor and increases the synthesis of s-adenosylmethionine (SAM-e), a nutrient that has powerful mood and sleep-cycle regulating properties. 

Energy/Metabolism Support: Plays a large role as a cofactor in enzymes involved in the metabolism of proteins, fats and carbohydrates, and is required to produce succinyl CoA, an intermediary in the Krebs cycle that generates cellular energy in the form of adenosine triphosphate (ATP). Due to its role in the production of ATP, vitamin B12 deficiency is often characterized by fatigue and weakness.

Musculoskeletal Health/Anti-Aging/Neurotransmitter Support: Supports the formation of the protective myelin sheath, the insulating exterior that speeds up nerve cell transmission, improvement in muscle aches, fatigue, sensitivity to pain, circulation, muscle cramps and reflexes.Due to B12’s ability to increase the production of neurotransmitters and nerve cell transmission, B12 has been shown to improve cognitive function

Cardiovascular Health:Important with maintaining healthy homocysteine balance is crucial for supporting arterial and cardiovascular health. 

Sleep Support:Modulates melatonin secretion and helps to normalize the sleep-wake cycle. It is a required nutrient for the biosynthesis of melatonin, the hormone that helps induce sleep.

Typical Population that would benefit from B12:Vitamin B12 is important in the maintenance of our metabolism, blood cells, nerve function as well as DNA health. It also helps your body produce energy by converting carbohydrates into glucose.Certain health conditions such as intestinal or stomach problems/previous gastric surgeries or malabsorption issues, poor nutrition (think of semaglutide patients) ,cancer, HIV, pregnancy, elderly, veganism, and alcoholism can cause vitamin B12 deficiency.
